What symptoms to expect after four days of quiting drugs?

Depends: Withdrawal symptoms (the reaction you have after you quit drugs) are dependent upon the drug that you quit. For instance, tobacco withdrawal: anger, irritation, weight gain, depression, restlessness, and anxiety are common symptoms. Please see your physician if you plan on quitting as some of these symptoms can be avoided with proper treatment.

Hard 2 say: Depends on drugs how much taking and reasons you were taking them check with your doc or his/her office nurse.

Depends on the drug: It really depends on the drug you've abruptly quit. For most drugs, the withdrawal symptoms are usually opposite of the drug's effects, e.g. Withdrawal from a stimulant will usually result in CNS depression, apathy, low energy, etc. Withdrawal from a sedative will cause CNS excitation. Certain drugs (especially benzodiazepines) are dangerous to quit abruptly and should be gradually tapered.

Be careful: It depends on the drug. Getting off some just will make you miserable. Stopping some cold turkey can kill you. Check with your doctor before stopping any drugs legal or not.
